Yellowstone National Park’s thermal features can be seen as the product of millions of years of geology at work. Geysers are hot springs that erupt periodically. The eruptions is the result of super-heated water below-ground becoming trapped in channels leading to the surface.

Thermal area of limestone and travertine formations in Yellowstone National Park
Yellowstone National Park sits on top of a dormant volcano and is home to more geysers and hot springs than any other place on earth. Wonders abound at this truly unique national park, from sites like the Yellowstone Grand Canyon to wildlife like America's largest buffalo herd, grizzly bears, and wolves.
Castle Geyser was named in 1870 by the Washburn-Langford-Doane Expedition due to its striking resemblance to the ruins of a castle. It has one of the oldest and largest sinter cones in Yellowstone, indicating that it has been active for thousands of years.

The Great Plains meet the Rocky Mountains in Wyoming. The state is a great plateau broken by a number of important mountain ranges. In the northwest are the Absaroka, the Owl Creek, Wyoming, Gros Ventre, Wind River and the Teton ranges. In the north central are the Big Horns; in the northeast, the Black Hills; and in the southern portion of Wyoming, the Laramie, Medicine Bow and Sierra Madre ranges.
